摘要：

We use a multiannulus accretion code to investigate debris disks in the terrestrial zone at 0.7 - 1.3 AU around a 1 M. star. Terrestrial planet formation produces a bright dusty ring of debris with a lifetime of greater than or similar to 10(6) yr. The early phases of terrestrial planet formation are observable with current facilities; the late stages require more advanced instruments with adaptive optics.
